TANDEM-SPRlNG DRAFT-RIGGING FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 792,147, dated June 13, 1905.

Application filed September 16, 1904-.- Serial No. 22 L666.

To all 1071 0721, it may concern.-

castings may be very securely and firmly at-.

tached to the car-framework and the strains more completely and evenly distributed than heretofore, thus adapting the draft-rigging to successfully withstand without danger of giving way in any part the extremely-heavy blows or strains to which draft-rigging is subjected in practical use upon the large modern cars carrying heavy loads and coupled in long trains.

My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with the customary draw-bar, tandemsprings, and followers, of side plates or stopcastings having-"the;customary stops for the followersto abut against and provided each with a longitudinal flange at its lower edge fitting under the draft-timber or sill to which the stop casting is secured and having a shoulder at its front end to abut in buffing against a corresponding shoulder on the drafttimber or car-sill and also furnished with a flange or shoulder to abut against the front end of the draft-timber or sill and a still further shoulder to abut in pulling against the cross-sill of the car-framework. The lateral longitudinal flange on the stop-casting and the shoulder near the front end thereof are below the line of draft, the horizontal plane extending centrally and longitudinally of the draw-bar and axially of the springs, while the flange or shoulder at the front end of the stop-casting is centrally thereof, so that the stop-casting has a direct abutment against the drafttimber or framework of the car both in the line of draft and also below the line of draft, and thus prevents any downward or wrenching strain being exerted upon the bolts by which the draft-rigging is secured to the carframe. The side plates or stop-castings are thus in my invention furnished with shoulders or abutments that bear against the carframeworl: both in pulling and bufiEing and below the line of draft, as well as in the line of draft.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.

In the accompanying drawings, forming a 5 part of the specification, Figure l is a side elevation, partly in longitudinal vertical section, of a draft-rigging embodying my invention. Fig. 2 is a plan view, partly in horizontal section. Fig. 3 is a cross-section on 7 line 3 3 of Fig. 2, and Fig. 4: is a detail perspective View of one of the side plates or stopcastings.

In the drawings, A A represent the center sills; A A, the draft-timbers or sills to which 7 5 the side plates or stop-castings are directly secured; A the front or cross sill; A the buffer-block; A*, the buffer-plate, and A the carry-iron.

B is the coupler; B, the draw-bar; B", the 0 draw-bar extension, the same being preferably in the form of a yoke or strap secured to the draw-bar by bolts or rivets I).

C C C (1* are the followers, and E E are tandem-arranged springs interposed between 5 each pair of followers.

D D are the side plates or stop-castings, each of the same having shoulders or stops cl cl (Z for the followers to abut against, an upper integral guide (Z and a lower remov- 9 able guide d, between which the followers reciprocate. The removable guide or plate d" is secured in place by short bolts (Z the heads (1 of which fit in slots (Z in the stop-castings. Each of the side plates or stop-castings D is provided with a horizontal laterally-extending longitudinal flange D at its lower edge, which fits under the draft-timber or sill A, and with a step or shoulder D which is below the line of draft and which abuts against a corresponding shoulder or step a on the draft-timber A. By reason of this shoulder D the front portion D of the lateral flange D is above the main portion thereof, and a vertical strengthening-web D connects and strengthens the two portions D D of this lateral flange. The stop-casting D is also provid ed with an end flange or shoulder D", which abuts against the front end of the draft-timber or sill A, and thus forms an additional abutment of the side plateor stop-casting against the d raft-timber. This abutting shoulder D is in the horizontal line of draft and extends above and below the same. The stopcasting D is also provided at its upper edge near its front end with a shoulder D, which abuts against the front or cross sill A and thus materially aids in resisting pulling strains, while the shoulders D" and D effectually resist buffing strains. The side plate or stop-casting D is also preferably provided with abutment projections D which lit in corresponding gains or notches in the draft-timber. The rear end of the side plates or stopcastings I) also abut against a filling-block A, extending between the center sills. The side plates or stop-castings D are also provided with upright wings or extensions D, which fit against the inner faces of the cross-sills A A and to which the same are secured by bolts F. The side plates or stop-castings D are further secured to the center sills and. drafttimbers by the upright bolts F and the horizontal bolts By my invention, as the side plate or stopcasting is provided with an abutting shoulder at its lower edge or below the line of draft and also with a lateral longitudinal flange, the side plate or stop-casting is thus not only itself very greatly strengthened, but it is also adapted to be secured to the car-frame in exceedingly strong manner and in a manner which relieves the bolts from wrenching strains.

I claim 1. In a tandem-spring draft-rigging, the combination with a draw-bar, draw-bar exten sion, springs, followers and side plates or stopcastings, having stops for the followers to abut against, and provided each with a laterallyextending longitudinal flange fitting under the draft-timber or sill, and provided with an abutment or shoulder bearing against a shoulder on the under side of the draft-timber or sill, substantially as specified.

2. In a tandem-spring draft-rigging, the combination with a drai -bar, draw-bar extension, springs, followers and side plates or stop castings having stops for the followers to abut against, and provided each with a laterallyextending longitudinal flange fitting under the draft-timber or sill, and provided with an abutment or shoulder bearing against a shoulder on the under side of the draft-timber or sill, each side plate or stop-casting having also a flange at its shoulder or front end bearing against the front end of the draft-timber or sill, substantially as specified.

3. In a tandem-spring draft-rigging, the combination with a draw-bar, draw-bar extension, springs, followers and side plates or stopcastings having stops for the followers to abut against, and provided each with a laterally extending longitudinal flange fitting under the draft-timber or sill, and provided with an abutment or shoulder bearing against a shoulder on the under side of the draft-timber or sill, each side plate or stop-casting having also a flange at its shoulder or front end bearing against the front end of the draft-timber or sill, each side plate or stop-casting being also furnished with a shoulder at its upper edge or side bearing against the front or cross sill of the car, substantially as specified.
